BIOL chapter 9 terms

TermDefinition
Abiotic Factors Non-living environmental components affecting organisms
Aphotic Zone Deeper ocean layer without sufficient light
Aquatic Biomes Water-based ecosystems influenced by depth, flow, and chemistry
Benthic Zone Bottom of aquatic ecosystems
Biome Major ecological community defined by climate and vegetation
Biosphere Global sum of all ecosystems; all regions where life exists
Biotic Factors Living components affecting organisms
Climate Long-term patterns of temperature, precipitation, and other conditions
Community Ecology Study of interactions between species in a community
Coniferous Forest (Taiga) Cold biome dominated by evergreen trees
Coral Reefs Highly diverse marine ecosystems built by coral animals
Desert Biome with very low precipitation
Disturbance Event that disrupts ecosystem structure and function
Ecology Study of interactions between organisms and their environment
Ecosystem Ecology Study of energy flow and nutrient cycling between organisms and environment
Ecotone Transition area between two biomes
Epilimnion Upper warm layer of water in lakes
Estuaries Areas where freshwater mixes with saltwater
Freshwater Biomes Aquatic systems with low salt concentration
Global Air Circulation Movement of air driven by solar heating differences
Global Ecology Study of biosphere-level processes
Hadley Cells Tropical atmospheric circulation cells causing heavy rainfall at equator
Hypolimnion Lower cold layer of water in lakes
Intertidal Zone Area between high and low tide lines
Lakes and Ponds Standing freshwater bodies with stratification
Limiting Factors Resources or conditions that restrict population growth
Marine Biomes Saltwater ecosystems covering most of Earth
Microclimate Local environmental conditions differing from surrounding area
Net Primary Production (NPP) Energy available to consumers after respiration
Ocean Currents Large-scale movement of ocean water affecting climate
Organismal Ecology Study of how individual organisms interact with environment
Pelagic Zone Open water region of oceans away from bottom
Permafrost Permanently frozen subsoil layer
Photic Zone Upper ocean layer where light penetrates
Population Ecology Study of factors affecting population size and dynamics
Primary Production Conversion of solar energy into chemical energy by producers
Rain Shadow Effect Dry conditions on leeward side of mountains due to precipitation loss
Rivers and Streams Flowing freshwater systems
Savanna Tropical grassland with seasonal rainfall
Solar Radiation Primary energy source driving climate and ecosystems
Temperate Forest Biome with moderate precipitation and deciduous trees
Temperate Grassland Biome with moderate rainfall and seasonal temperatures
Terrestrial Biomes Land-based biomes defined by climate and dominant vegetation
Thermocline Zone of rapid temperature change between layers
Tropical Forest Biome with high rainfall and stable warm temperatures
Tundra Cold, dry biome with permafrost
Turnover Seasonal mixing of water in lakes redistributing oxygen and nutrients
Upwelling Process where deep, nutrient-rich water rises to surface
Weather Short-term atmospheric conditions
Wetlands Land saturated with water supporting unique vegetation

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
